SPECIFICATION forming art of Letters Patent No. 699,919, dated May 13, 1902. Application filed Angust 19, 1901. gerifll NO- 7 (N0 model) To all whom it may concern:

Be it known that I, 1\'IIOHAEL HABERLE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New 5 York, have invented certain new and useful Improvements inWindows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the class of windows in which the sash are hung for swinging about a horizontal axis to admit of cleaning, replacing broken panes, ventilating, or other desired purpose and which are counterbalanced and have a" free sliding movement in the casement or'frame.

The invention consists of the novel. features, details of construction, and combinations of the parts, which hereinafter will be' more fully described, illustrated, and finally embodied in the claims.

I Corresponding and like parts are referred to in the following description and indicated in'all the views of the drawings by the same reference characters.

The window frame or casement 1 may be of any construction and size and is provided with upper and lower sliding sashes counterbalancedin any selected way. The sashes are similarly mounted so as to swing from the vertical abouta'horizontal axis to admit of the panes or lights being readily reached for cleaning or other desired purpose. The sashes are hingedat their lower ends to the slidable bars either directly or by means jof a connecting cross-bar. The slidable bars 2, one for each side of I the frame or casement and a pair for each sash ,"are arranged in the spaces or vertical guidegrooves provided between the stops of the easement, and the counterbalance is connected directly thereto either by means of ach'ain or cord. Inasmuch as each slidable {bar and the adjunctive parts are similarly constructed, a detailed description of one only will be given. Theslidable bar 2 has a vertical slot 3, which is enlarged at one end to admit of the head of the slideblock 4;,passing therethrough when placing the slide-block in position for running movementiintheivertical slot. Opposite sides of the bar 2 arecut'a'way, and the side adjacent the jamb of'the casement is grooved to receive the chain, cord, or like connection between the counterbalance and the slide-block. The lower end of corresponding bars 2 has connection with the lower end of the sash and Fig. 14 is a detail view in' is prevented from inward displacement, and in order to prevent inward movement of the upper ends of the bars 2 when the sash is swung from a vertical position keepers 5 are secured to the upper ends of the bars 2 and have projecting ends, which enter and operate in grooves 6, formed in the inner sides of the stops. A bar 7 connects the sash with the slide-block 4 and limits the swinging movement of the sash. This bar '7 has pivotal connection at one end witha stile of the sash, and its opposite end has pivotal connection with the slide-block. A T-shaped lug 8 is provided upon the side of the block 4, designed to face the window-opening and cooperates with an opening 9 to pivotally connect the bar 7 to the slide-block. The opening 9 is oblong and arranged crosswise of the bar 7 and is medially arranged with reference to a round countersink formed in a side of the said bar to receive the arms of the lug 8 and admit of the end of said lug coming flush with the side of the bar 7. When the bar 7 is turned to bring the opening 9 in coincident relation with the T-shaped lug 8, the bar may be fitted to or removed from the slide-block, and when fitted to the said slideblock and the lug S has passed through the opening 9 a turning of the bar 7 will cause the arms of the lug 8 to engage with the countersinks at the sides of the said opening 9 and prevent separation of the parts 4 and 7. The bar 7 is of a width to overlap the edge of the vertical slot 3 and prevent outward displacement of the slide-block 4. Inward movement of the slide-block is prevented by oppositely-disposed wings 10 at opposite ends of the block. Opposite wings or extensions 11 are provided at the inner side of the block at the end opposite the lug 8 and constitutes a head to overlap the sides of the slot 3 and in conjunction with the bar 7 prevent outward displacement of the slide-block. This head 11 is adapted to pass through the enlarged end or portion of the slot 3 when placing the slide-block in position or removing it from the slide-bar 2.

Then a chain 12 is employed as the connecting means between the counterbalance and the slide-block, the latter is formed with an apertured car 13 for connection of the chain therewith; but when a cord or rope It is employed for connecting the counterbalance to the slide-block the latter is modified in construction to the extent of replacing the apertured car 13 by a notched lug 15 for the reception of the said cord, the knot lying in the space formed between the lug 15 and the end portions of the block carrying the T- shaped lug 8. By having the lug 15 notched in its side the cord or rope can be readily placed in position or removed from the block without the inconvenience resulting from such constructions as require the threading of the cord through an opening or passage. The open side of the notch is closed by a side of the slot 3, into which the notched lug extends when the slide-block is in position.

The fastening means for connecting the swinging end of the sash to the free ends of the slide-bars consist of complementary members 16 and a lock-pin 17. The members 16 are of like construction and are formed with projections 18, which are beveled upon the sides adjacent the part to which the members are attached, so that when closing the sash the slide-bars are simultaneously drawn close against the edges of the said stiles. These beveled projections overlap when the sash is closed and have corresponding openings 19 to receive the inner end of the lock-pin 17, which is slidably mounted in the side stile of the sash. B y having the lock-pin pass through the beveled projections 18 of the members 16 of the fastening the opening in the slide-bar and side stile of the sash is not enlarged or worn, the parts 16 acting as wearplates. One end of the lock-pin is bent to provide a finger -grip 20, and the opposite end is rounding, so as to pass through the openings 19 and snugly fit the same, so as to prevent any possible movement of the sash with reference to the corresponding slidebars. The intermediate portion of the lockpin is flattened, as shown at 21, and operates in the narrow portion of the keyhole-slot 22, formed in the plate 23,attached to the side stile of the sash. By having the flattened part 21 of the lock-pin arranged to operate in the narrow portion of the keyhole-slot 22 the fingergrip is maintained in a given position and the lock-pin is limited in its sliding movemeuts. The enlarged end of the keyhole-slot 22 of the plate 23 is out of register with the opening in the side stile of the sash when the said plate 23 is secured thereto.

The slidable bars 2 are connected with the sash, so as to move in unison, thereby preventing any binding of the sash or slide-bars when moved up or down in the frame or casing. In the case of a direct connection between the sash and slide-bars the means eonsist of members 24 and 25, pivotally connected, the member 24 being rigidly attached to the slide-bar and the member 25 being firmly attached to the horizontal rail of the sash. Each member of the hinge connection comprises right-angularly-disposed parts, a boss or reinforcement 26 being formed or provided in the angle between the parts and these reinforcements 26 being apertured in coincident relation to receive the pivot-pin 27. The hinge connection is such that when properly applied the sash and slide-bars must move up and down in a manner similar to a rigid structure. The vertical portions of the hinge members are let into mortises and slide-bars so as to come flush therewith and admit of these parts coming close together. In another form corresponding slide bars 2 are connected at one end by means of a cross-bar 28, which is rigidly attached at its ends to the bars 2 in any substantial way. The sash is hinged to the transverse connecting-bar 28 by any form of hinge 29. While the sashes can be mounted to swing either in or out or up or down, it is preferred to have them swing inward and downward.

By having the swinging sashes connected to the slide-blocks by means of the brace-bars 7 and by having the counterbalancing means connected with the said slide-blocks the counterbalance in addition to holding the sash at any elevation also serves to materially assist in holding the sash open to any desired angu lar adjustment and facilitates the swinging of the sash when opening and closing it by a swinging movement.

The inner stop of the casement has a vertical groove 30, which is adapted to cooperate with the lock-pin so as to hold either sash open for ventilating purposes and prevent its closing by a draft. When the sash is swung inward at its upper end and the inner end of the lock-pin 17 is entered into the vertical groove 30, the sash cannot be closed or opened farther by means of a draft, and this is of material advantage in stormy weather. The provision of the vertical groove 30 admits of the sash being moved up and down without necessitating the closing or swinging of the sash into the plane of the slidebars 2.

Having thus described the invention, what is claimed as new is 1. In a window, andin combination with slidable bars, a sash having hinged connection therewith, and a slide-block having a T-shaped lug, a brace-bar having pivotal con nection at one end with the sash and provided at its opposite end with an oblong opening and a round countersink for reception of the arms of the T-shaped lug after the latter has passed through the said oblong opening, substantially as set forth.

2. In a window, and in combination with slidable bars, and a sash having hinged connection therewith, a fastening comprising complementary members secured to, respectively, the slidable bars and side stiles of the sash andhaving cooperating beveled portions, and a lock-pin applied to a side stileof' the sash to pass through corresponding openings in the said members of the fastening, substantially as set forth.

3. In a window, and in combination with slidable bars, and a sash having hinged connection thereto, a lock-pin slidably mounted in an opening formed in a side stile of the sash for securing the latter when closed, said pin having an intermediate flattened portion, andan escutcheon-plate having a keyholeslot and secured to the side stile of the sash with the flattened portion of the lock-pin arranged to operate in the contracted portion of the said keyhole-slot, substantially as and for the purpose set forth.

4. In a window, and in'combination with slidable bars having vertical slots, a sash having hinged connection with the said barsso as to swing open and shut, slide-blocks having notched lugs for reception of the knotted end of the rope or cord leading from the counterbalance, said blocks mounted for sliding movement in the aforesaid vertical slots and having the open sides of the notches closed by a side of the said slots, and bracebars connecting the slide-blocks with the hinged sash, substantially as set forth. I
